Uncaught TypeError: Cannot convert undefined or null to object 0.92.0 #3125

Closed stepanov1975 closed 5 years ago

stepanov1975 commented 5 years ago

Home Assistant release with the issue: 0.92.0 Last working Home Assistant release: 0.91.4 Lovelace UI Browser and Operating System: Google Chrome Windows 10 Description of problem: Error in log after displaying the history. No visible issues. This not appeared in 0.91.4, but I am not sure because I added some additional sensors before updating to 0.92.0 and not sure if I checked history.

Javascript errors shown in the web inspector (if applicable):

What mode are you in?

Mode? Lovelace as mentioned. Or you mean something else?

I get this error every time I open the ZWave menu. My ZWave network also started acting up when I started seeing this error, trying to figure out if they're related.

I have a ZWave sensor reporting motion, but none of my automations fire that use it as a trigger.

Just want to add that I get the same error when clicking on:

Both with 0.92.2 and 0.93

capstan1 commented 5 years ago

And another addition: I just deleted all the views from my lovelace and just added a Entity card with 3 lights. I also changed to the default theme and - to make sure - rebooted. The error keeps appearing, so it doesn't seems to be the issue of some custom card.

kloggy commented 5 years ago

I just want to chime in here and say that I too am experiencing this. YAML mode here too.

Also, I'd like to add that this is probably much more widespread than is realised. Functionality is not impaired* along with the fact that the (improved) way that hassio only shows one instance of repeating errors with a count means many will not even know it is happening.

*Except last night while testing and so forcing loads of errors I was exceeding some limits which did cause that 'Log write failure...'(?) error which in turn produces a pop-up notification (bottom left of the window). Sometimes this even caused a 'reconnection'

I don't have much to add in the way of details except to say that after many hours of investigation last night I am no nearer to finding the cause. I had suspected custom cards but am not convinced by that anymore as I also get these errors by going to History and Logbook.

I encounter the same issue -- it occurs at least once every reboot:

starkillerOG commented 5 years ago

I am getting verry similar errors: http://192.168.1.???:8123/frontend_latest/app.a259a502.js:2:59245 TypeError: can't convert undefined to object shows up 32 times.

With me those errors show up predominantly when I open my vieuws that contain input datatime entities.

Home Assistant release with the issue: 0.92.2 Lovelace UI, default mode (configuration in frontend) Browser and Operating System: HA: Pi3B Hassbian Browser: both on firefox 67.0 (windows 10) and on safari (Android smart phone)

araczkowski commented 5 years ago

I noticed the same in 0.93 it is related with input_number/slider(paper-progress) on lovelace card

iron-a11y-keys-behavior.js:423 Uncaught TypeError: Cannot convert undefined or null to object at Function.keys () at HTMLElement._listenKeyEventListeners (iron-a11y-keys-behavior.js:423) at HTMLElement.attached (iron-a11y-keys-behavior.js:319) at HTMLElement.attached (class.js:384) at HTMLElement.connectedCallback (legacy-element-mixin.js:110) at NodePart._insert (parts.ts:222) at NodePart._commitNode (parts.ts:230) at NodePart._commitTemplateResult (parts.ts:264) at NodePart.commit (parts.ts:204) at render (render.ts:56)

probably an error in PolymerElements: https://github.com/PolymerElements/iron-a11y-keys-behavior/issues/93

I can cause this error to occur whenever I load a Lovelace card with a history graph but only if refresh_interval is defined.

Generates the error:

cards:
  - entities:
      - entity: input_select.lounge_ac_mode
    show_header_toggle: false
    type: entities
  - card:
      entities:
        - input_select.lounge_ac_mode
      refresh_interval: 300
      type: history-graph
    style:
      border: solid 2px var(--primary-color)
      transform: scale(0.975)
    type: 'custom:card-modder'
  - columns: 3
    entities:
      - entity: sensor.lounge_room_temperature
      - entity: sensor.lounge_room_humidity
      - entity: sensor.lounge_room_condensation_chance
    show_name: false
    type: glance
title: Aircon Control
type: 'custom:vertical-stack-in-card'

Does not generate the error:

Same problem here. opening any More info card produces the error. 94.0 storage mode

daveyrb commented 5 years ago

I get this whenever I look at History or Logbook: V0.94.0

GaryOkie commented 5 years ago

Can confirm - hassio 94.1 error occurs when viewing history or logbook using Chrome (v75.0.3770.80). Tried FireFox - no errors.
